Ghostshield Siloxa-Tek 8505 Ultra Concentrate (1 Gallon Makes 4 GALLONS) – Penetrating Concrete Sealer, Water, Salt & Oil Repellent

Ghostshield Siloxa-Tek 8505 Ultra Concentrate (1 Gallon Makes 4 GALLONS) – Penetrating Concrete Sealer, Water, Salt & Oil Repellent

A tenacious and versatile sentinel—all the heart of Siloxa-Tek 8500 with added oil resistance. Use with the Lithi-Tek 4500 densifying primer for increased performance and longevity.

• An industrial-grade, water-based, silane/siloxane engineered to reduce water and moisture intrusion, protect concrete from deicing salts and chlorides, and resist staining from oil and fluids.
• Prevents deicing salt/chloride damage, freeze thaw damage, spalling, pitting, cracking, dirt pick up
• Resists staining from oils, auto fluids etc.
• Reduces moisture intrusion, water ingress and water vapor transmission
• Excellent penetration, easy application, no appearance change, low VOCs, water beading effect

Product Details:

• Excellent waterproofing – Penetrates deep within the concrete chemically reacting within the pores and capillaries creating a long-lasting hydrophobic surface that beads water
• Resists staining from oil and grease – Oleophobic fluorocarbon makes oil and grease easier to clean from treated surfaces decreasing maintenance requirements
• 100% breathable – Non-film forming. Allows moisture within the concrete to escape without adverse effects to the sealer. Does not trap moisture
• Reduces moisture intrusion – Resists wind-driven rain, prevents freeze-thaw damage, spalling, pitting and cracking.
• Resists atmospheric staining – Resists lichen, efflorescence and dirt pick up
• Improves durability – Prevents capillary uptake of water and the aggressive substances dissolved in it
• Natural flat finish – Does not change surface appearance, UV stable will not breakdown with light exposure
• Can be applied to cured, honed and polished concrete – Ideal for horizontal surfaces such as garage floors, compatible with silicate densifiers
• Water based – Low VOC’s

Surface Preparation: New “green” concrete must be properly cured. Concrete should obtain 80% of design strength, typically achieved within 14-28 days. The concrete substrate must be structurally sound and clean of oil, grease, dirt, wax, curing compounds, efflorescence, paints, previous sealers, adhesives and other contaminants that might interfere with the penetration of the sealer. Power wash, acid etch or mechanically scarify as necessary to achieve the desired surface condition. Allow for proper dry time before application. The surface-zone moisture content of the concrete should not exceed 4% wt. Do not apply if standing water is visible. Surface and air temperatures must be at least 40°F during application. Surface and air temperatures should not exceed 95°F. Do not apply when temperatures are expected to fall below 32°F within 8 hours or when rain is expected within 12 hours following application. Keep material from freezing. If freezing conditions exist before application, let the substrate thaw before application. Do not apply during inclement weather or when inclement weather is expected within 12 hours. Crack, patching and expansion joint sealants can be applied before or after application; always test for compatibility and adhesion. Protect people, property, vehicles, window glass, roofing materials, plastic products, shrubbery, landscaping and all surfaces not set for treatment from overspray.

Application – Ultra Concentrate: Always test a small area before application to ensure desired performance, aesthetics, coverage rates and to verify application technique. Let test area dry thoroughly, 5-7 days, before inspection. Always mix the concentrate with 3 parts water prior to application. Distilled water is recommended for maximum performance. Stir material throughly before and during application. Two wet-on-wet coats are needed to ensure complete coverage. Apply with a roller, brush or low-pressure non-atomizing sprayer. Apply to saturation and let the first coat penetrate for 5-10 minutes then reapply a second coat in the same saturating manner. Less material will be needed for the second coat. Roll or broom out any puddles until the sealer penetrates the substrate. If it starts to rain, stop treatment and cover the impregnated areas.

Dry Time: Typical drying time is 4-6 hours at 70°F and 50% relative humidity. Cooler temperatures or higher relative humidity can extend the drying time. Treated surfaces will be ready for pedestrian and vehicle traffic within 24 hours. Water repellency will continue to develop within 7 days of application.

Clean Up: Clean equipment, tools and surfaces with hot soapy water. Unused or old material may be disposed of in a waste disposal site in accordance with local, state and federal laws.

Precautions/Safety: Avoid contact with skin, eyes and clothing, do not take internally. Use appropriate safety equipment during application and handling. Please refer to the safety data sheet (SDS) for additional precautionary instructions before use.

Best Performance: Proper application is the responsibility of the user. Will not inhibit water penetration through unsound or cracked surfaces with defective flashing, caulking or structural waterproofing. Spills should not be allowed to sit for extended periods of time, clean all spills in a timely manner. Make sure the most current versions of product data sheets and safety data sheets are being used.

Coverage: 1 coat: 150 – 400 square feet per gallon. 2 coats: 75 – 200 square feet per gallon. Variations in texture and porosity of substrate will affect the coverage and performance of the product.
